本文從長期經濟成長與福利的角度分析開放貿易的效果。本模型為一個兩國、兩財貨（消費財和投資財）和單一生產要素（資本）的總體內生成長模型。 模型中假定一國的產出除了受跨部門知識外溢效果的影響外，也會受跨國知識外溢效果的影響。在此架構下，我們發現在兩國極為相似且時間偏好率相當小的情況下，貿易開放有助於兩國長期經濟成長率的提升。 This paper studies the effect of trade open from the perspective of long-run growth and welfare in a two-country, two-good, and one-factor endogenous growth model. We find that trade open benefits the growth rates of these two countries when their model parameters are similar and the time preference rate of domestic country is small enough.
